CUTTER FOR BEVEL-CARDS.

SPEGIFICATIONformingpart of Letters Patent No. 572,320, dated December1, 1896.

Application filed May 11,1896. Serial No. 590,999. (No model.)

To all whom it may concern:

Be it known that 1, PAUL J. STUPARICH, a citizen of the United States,residing in the city and county of San Francisco, State of California,have invented an Improvement in Apparatus for the Manufacture of Bevel-Cards; and I hereby declare the following to be a full, clear, and exactdescription of the same.

My invention relates to an apparatus which is especially designed forforming beveled openings in cards or tablets which are designed forphotographic mounts and other purposes.

It consists in certain details of construction, which will be more fullyexplained by reference to the accompanying drawings, in which Figure 1is a perspective view. Fig. 2 is a side sectional elevation. Fig. 3 is aplan view of the mechanism adapted for cutting ovals. Fig. t is a detailview of the cutter and its holder. Fig. 5 is a part elevation and partsectional detail of the devices for cutting ovals.

The object of this invention is to provide a device by which beveledopenings of any degree of inclination, either circular or oval, may becut in the thick material which is employed for photographic mounts, orfor other purposes requiring such openings, so as to produce a smoothbeveled edge to the opening, the apparatus being adjustable to cut Thecenters which are thus cut out may also be utilized for other purposes.

A is a base-plate of any desired size, which may be made of metal, or ofsufficient rigidity to retain its shape, and mounted upon a table orproper support. Through opposite ends of this table slide the verticalstandards B, which have their lower ends fixed in a bar I) beneath thetable. This bar slides on guides 19 and is normally held up by springsd. A rod f from a treadle is the medium by which it is depressed atwill. A strong bar O is secured to the upper ends of the standards B.Through the center of this bar passes a vertical shaft D,the upper endof which shaft is guided and supported by a yoke C, fixed upon the topof the bar C, so that the vertical shaft is made to turn evenly andsteadily.

the shaft.

Upon the upper end of this shaft is a crank E, by which power may beapplied to rotate The shaft is vertically slidable through the yoke andbar 0, and between the crank and the yoke, or at other suitable point,is a spiral spring F, which acts to normally raise the shaft up, butwhich is compressible, so that the shaft may be pressed down at willwhen the crank is being turned. Upon the lower end of the shaft D is anenlarged hub D, and transversely through this is made an opening inwhich is fitted a slidable bar G. The end of this bar has secured uponit an enlarged head H, and through this head, transversely to the arm G,passes a short rod I. Through this rod I is made a hole to admit theshank J of the cuttingknife J.

The rod I is turnable in the head H, so that the cutter J maybe set atany desired angle, and the shaft J of the cutter may also be turned inthe rod I, thus giving a universal adjustment, besides allowing theknife J to be raised or lowered, as may be desired. The end of the rod Iupon the opposite side of the head H is screw-threaded, and a nut I fitsupon it. When this is screwedup against the side of the head H, it drawsthe shank J of the cutter J firmly against the opposite side of the headH, and thus locks the cutter in any position to which it may have beenpreviously adjusted, where it will be held firmly While the Work isbeing done. This adjustment enables me to set the cutter at any desiredbevel and angle, so as to cut to any desired depth below the head andaccommodate it to any thickness of material to be operated upon.

Below the bar C is the annular disk K, having arms K projecting inopposite directions and perforated so as to fit over the verticalstandards B, upon which these arms are fixed, so that the disk K can beraised or depressed at will and in unison with the movement-s of thesliding standards B and connected parts. The inner periphery of thisdisk has a beveled form, the bevel being approximately that which it isdesired to give to the card or mount to be operated upon. Beneath thisdisk L to suit the work to be done.

Upon the table A, directly beneath the openings in the disks, is secureda plate M, this plate being also removable so that different sizes maybe employed to correspond with the sizes of the beveled disks above. Inthe center of this plate is made an opening N, corresponding with theopenings in the disks above, so that the upper edge of the opening formsa support for the edge of the card to be cut when the latter is clampedthereon.

The disk K is by means of its arms K movable with the vertical standardsB, so that when a card has been placed upon the plate M the disk isdrawn down by means of the foot-lever connecting with the disk until itis pressed firmly upon the card to be cut. The knife J is now adjustedso as to move within the periphery of the beveled ring L, and when itsangle is properly determined it is locked in place by means of the nutI. The crank E is then turned, thus rotating the shaft D and head D andcausing the cutter J to traverse the inner periphery of the disk L andcut through the thick card until the center has been detached. The cardresting upon the ring M in such a manner that the edge of the knife justcuts through it interior to the ring and its upper surface beingcorrespondingly clamped by the disk L, the edge of the cut will beproperly supported, so as to be left perfectly smooth, and the cutter,which is made with a convex cutting edge,

will make a perfectly smooth bevel cut through a card of any thicknessup to a halfinch or more. These cards are especially constructed andbuilt up to a considerable thickness, and it is of importance to makethe face of the beveled cut as smooth and perfect as the surface of thecard itself.

Vhen it is desired to make an oval-cut, the mechanism shown in Figs. 3and 5 is used, which mechanism may be briefly described as follows: Fromthe shaft D extends an arm D having a socket at its outer end, intowhich enters and is guided the stem d, the latter carrying on its outerend the head D. This head carries at its bottom the pinion g, whichmeshes with the oval gear G. This pinion g is held in contact with thelarge gear by means of the spring or springs g. Secured to the upperportion of this head D is the stem G, which carries the head H. 'Asetscrew in the head D holds the stem G firmly in the desired position.It will be seen by this construction that by turning the crank E the armD with its pinion will follow the periphery of the gear G, the springs gholding the gear 9 constantly against the gear G, and the socket in thearm D allows the stem d to move in and out freely. The knifecarryinghead H being fixed rigidly to the pinion-carrying head D will cause theknife to describe exactly the same contour as that of the large gear G.These parts may be re versed to advantage by putting the gear G andpinion g above and the head D below.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. An apparatus for cutting beveled openings in cards and tablets,consisting of a table, a removable plate secured thereon having abeveled central opening, a verticallymovable clamping-plate having abeveled opening made centrally therein, a vertical shaft turnable abovethe clamping-plate, a. transversely-adj ustable bar carried by theshaft, having a head upon its'outer end, a cutting-blade and a means forclamping it to the head so as to stand at the desired angle, and a meansfor rotating the shaft and blade.

2. An apparatus for cutting beveled openings in cards and tabletsconsisting of a table, a base-plate having a central opening, avertically-movable clamping-plate and guides upon which it is movable,said clamping-plate having a beveled opening made centrally therein, anadjustable supplemental plate fixed beneath the clamping-plate, avertically movable and rotatable shaft having a head at its lower end,an arm transversely adjustable in said head, having a head at its outerend, a rod extending through said head having an opening upon one sideto receive the shank of the cutter-blade and a nut fitting thescrewthreaded opposite end whereby the blade may be turned and clampedat any desired angle.

3. An apparatus for cutting beveled openings in cards or tablets,consisting of a table, a removable plate fixed thereto having a centralopening, a cross-bar supported and vertically movable above the plate,with journals for a vertically-rotatable shaft, an arm carried by thelower end of the shaft and adj ustable transversely thereto, with anangularly-adjustable cutter at the end, a spring by which the verticalshaft is normally held up, said spring yielding to allow the shaft andcutter to be depressed, a disk having a beveled central opening, and amechanism by which the disk is movable to clamp the tablet to beoperated on between itself and the lower perforated plate.

In witness whereof I have hereunto set my hand.

PAUL J. STUPARIOH.
